2012 F150 Ford Transmission issues
If I am in traffic or at a stop light the trans starts to act up. I have to rev it up to get it in higher gears. Once in 5th, if I take my foot off gas it drops to 3rd and rpms go up. If in 6th, it drops to 4th and rpms go up. If at stop light, I take foot off brake, will not start moving only makes groaning sound and jerks.
Checked fluid and updated software. No codes were present and no yellow wrench.
